Digital light processing is used in televisions and video projectors. It was developed by Dr. Larry Hornebeck in the year of 1987. It is one of the best technologies in digital cinema projection. It is the combination of LCD and LCos. There are two methods involved in DLP projection systems such as single chip DLP projectors and three chip projectors. It is used to create color image. These components are used to make colors. It has color wheel. It is divided into many colors such as red, green and blue. These colors are primary colors. The secondary colors are cyan, yellow, white and magenta. The color performance of the secondary color is called as the brilliant color. The whole system gets light digitally from an optical semiconductor called as Digital Micro mirror Device. It comes in one or three chip models. The cost of digital light processing varies from model and manufacturer.
